I was looking to install Mac OSX Sierra on my Dell XPS 13 9370 but looking through this form I come to find that it might not be possible since the killer wireless card is soldered onto the board. I was wondering why this would prevent me from installing/using sierra on my machine. Is it just that drivers for the killer wireless chip set don't exist for OSX? I have Ubuntu Artful Ardvark installed on it and the generic drivers seem to work just fine. Why is it that you couldnt use those drivers for OSX?

oops..it looks like I uploaded the wrong config file.
I am using the config file of "config_HD615_620_630_640_650.plist" from your below link as I am running 10.13.https://github.com/RehabMan/OS-X-Clover-Laptop-Config
however my laptop keep rebooting during loading bar screen, once I revised the FakeID to the invalid one, it boots up.
no idea which FakeID should I use...
could you do me a favor, show me what is wrong? thanks a lot.

Killer Wireless drivers are available in Linux, but not (completely) in source code form. It's up to KW to git a fully open source repo, and a kind soul to write a kext wrapper for them. Neither are easy, unfortunately. Then there's the issue of KW performance, which I won't go through here...

You *can*, however, purchase a USB wifi card that will work for macOS (most likely USB-A, not USB-C); it will add to the battery life drain and you will have to carry it around. But the right USB card will work in Ardvark and macOS and let you do a lot of interesting things under Linux as well...

I'll add:
Have a look at one of my previous replies. I have documented a way of using thre internal USB header to connect a small USB device (in my case, a Logitech Unifying receiver). On 9370, you have to discover whether that header is still predent. I suspect it is, since there's the (unused) touch-screen.
It may be a way to integrate a small (and underperforming) USB wifi card...
